The Muncie SH8 Series Power Take-Off, part number SH8S-M6512-E3EX or SH8SM6512E3EX, is an air-shift-only PTO engineered for high-torque truck applications. Built on the SH Series platform, it bridges the gap between Muncie's TG and 82 Series PTOs. The 8-bolt cast iron housing simplifies mounting and holds up under demanding duty cycles. An integral air shift design keeps the air cylinder enclosed, eliminating an exposed external cylinder. Seventeen input gear sets cover most popular transmission configurations, while five speed ratios and 12 output shaft options give installers broad flexibility to match the pump on hand. Intermittent torque ratings vary by speed ratio, reaching up to 400 lb-ft at ratios 05 and 07. Available from Pro Gear and Transmission. Call us to confirm proper fit for your application.
